Because those who are led by the sons of God. are
The greatest sign that you and I are maturing in our walk with God is when we can discern the difference between "good things" and "God-things." When the people of Israel journeyed out of Egypt through the desert, they were led by the cloud by day. They could move only as fast as the cloud. If they went ahead, they went without God's presence. If they lagged behind, they also lost God's presence.
Each of us must have the discernment to know when God is leading in a matter, or if it is simply a good idea. There are so many things in which you and I can be involved, and the more successful you become, the greater the temptations to enter into things where God has not called you. Entrepreneurs are especially prone to see all the opportunities.
I recall one time when I entered into a project that I thought was a great idea. It would help many people. After two years, the project had to be discontinued. It was a great lesson on understanding what projects have God's blessing on them. There are some projects you and I might get involved in that result in little fruit compared to the investment put into them. That is because they may never have been birthed by the Holy Spirit.
As sons of God, we are called to be led by the Spirit. This requires a level of dependence on God in which many of us really do not want to invest. It requires listening, waiting, and moving only when God's Spirit tells us to move. Businesspeople are "action" people. We know how to get things done, but our greatest strength can be our greatest weakness.
Today, ask God to make you a Romans 8:14 man or woman who is led by the Spirit of God. Pray against lagging behind or moving ahead. Ask God to reveal whether the next project you consider is a "good thing" or a "God-thing."
